Vulnerability Overview

The Royal Elementor Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'status' parameter in the wpr_update_form_action_meta AJAX action in all versions up to, and including, 1.7.1056. This is due to insufficient input sanitization and output escaping, combined with a publicly leaked nonce that allows unauthenticated access to the AJAX handler. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Royal Addons for Elementor <= 1.7.1056 carries this weakness at status, and reaching it takes no account at all. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Royal Addons for Elementor the fix is 1.7.1057: builds <= 1.7.1056 are affected, anything from 1.7.1057 onward is not.

Remediation

Update to version 1.7.1057, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Royal Addons for Elementor 1.7.1057 closes this, and updating the plugin is the step that ends it.
